TitleThe research of DC motor’s fuzzy-PID control
based on DSP
Abstract
Permanent magnet DC motor has been widely applied in industry, life and automobiles for its merits of speed adjustment and high starting torque。 One of the key technologies of the PMDC is the precise control of rotational speed which requires complex control algorithm。 Digital Signal Processor(DSP) has broad application prospect because of its advantages in computing capability and many peripheral functions。
This paper designs a two-dimension fuzzy-PID controller and establishes a PID simulation model of the speed adjustment system of PMDC。 The simulation is completed and compared with regular PID controllers。 According to the test-bed, the control system is designed including the hardware and the software。 The hardware includes the schematic drawing and PCB documents of the hardware circuit based on Altium Designer; using C language designs the main programs and interrupt service programs。 Last, completes software and hardware joint debugging, test results show that: the system test coincides the simulation results, and possesses high precision, fast response, small overshoot。
